T.G.
My daughter is 15 months and would chokeon table food until she was a year old. I couldn't even give her the gerber snacks. She had 4 front teeth but did not grasp the concept of chewing. She would even choke on stage 3 food.
I jsut kept offering table food like scrambled eggs, fried eggs, rice, pasta (cut up small), diced and boiled carrots.
Then one day out of the blue she started eating them without choking. Now she eats anything and everything (except beef - I don't give her that yet).
Some kids just take longer. He is only 11 months. No big rush.
If he goes over a year and still has issues, talk to your pediatrician. For now, just let him go at his own pace.
I think sometimes we try to rush our kids.
